Waste oil refineryplant not only extracts lube oil from minimal crude oil, but also employsnon-cracking evaporation (NCE) in front end treatment along with ReactivationClay Polishing System (RCPS) or Adsorbent Mineral Polishing System (AMPS) to polish output oils and restore their quality.
The procedure employs 4 liters of crude oil (instead of 160liters which was earlier used), to procure 2.5 liters of high quality lube oil.This method is significant with features such as low investment and maximum benefits and is thus the best option for re-refining needs.
The waste oilrecycling passes through primary, separation and finishing processes whichensure that the oil is dehydrated and avoids cracking in non crackingevaporation (NCE) unit.
The used oil re-refining system has a small footprint withlow conversion rates and adds to three times sales value of the oil.
Besides using any type of lube oil, the waste oilrecycling unit employs engine oils, used spindle oils, waste turbine oilsto extract refined oil.
The moisture is flash evaporated following which hydrocarbonstream is coated as a thin layer and is subjected to vacuum. When the boilingpoint of oil fractions is lowered, oils are segregated as low, medium and high, based on their viscosity.
The resulting sludge is also commercialized as asphalt andthus adds to the revenue. The oil thus obtained is further processed inReactivation Clay Polishing System, so that the oil’s properties are enhanced and yields high quality groups I and II base oils.
The waste oil refineryplant improves colour and odour of the oil, besides regulating its sulfurcontent. It also increases the oxidation resistance of the oil. The clay usedin this system can be used 500 times before it is considered unfit. The oil is subjected to numerous processes of distillation before reaching its optimum attributes.
Of the two waste oilrecycling treatments namely clay based finishing treatments and catalytichydro treatments, the latter is not only expensive but also is sensitive andrisky since it is done in high temperatures and high pressure levels.
The waste oilrefining plant ensures that the oil meets prescribed standards in terms ofviscosity index, constituents, sulfur content, colour, odour and oxidationstability. Adsorbent uses its polar attributes to remove unnecessary compounds from the oil, which accentuates shelf life of the oil.
RCPS also switches from parallel to series mode and easilyswitches between processing modes for each reclaimed stream.
Waste OilRefinery Plant is advantageous with attributes such as low costs, flexibleoperating modes, accommodation of all voltages and frequencies, standardindustrial waste and customization to plant size.
The above mentioned attributes make RCPS and AMPS waste oilrecycling method advantageous in terms of economic and environmentalperspectives. The waste oilrefinery plant mitigates sulfur to 300 PPM from its original quantity of2000 PPM in the contaminated oil. The oil thus obtained is stable againstoxidation for desired time and is refined satisfactorily.
